*1: In high-speed logging mode, data is recorded in 83 ms at 60 Hz and in 100 ms at 50 Hz.
*2: Momentary power and integrated power values are converted from the measured current.
Correctly specify the number of used channels, applicable measurement target circuit, CT
type, frequency, voltage and power factor.
*3: The display turns OFF after 10 seconds of no user operation and recovers by a key
operation when SLEEP mode is specified. LAN cannot be used when sleep mode is
specified.
*4: Automatically writes the data to the SD memory card when the internal memory reaches its
capacity and continues recording until the SD card memory capacity reaches its limit. The
unit stops operation if there is no SD memory card inserted when the internal memory
reaches its capacity. (Recording can be resumed after inserting an SD memory card and
